BRUSH.

SPECIFICATION forming part of Letters Patent No. 349,649, datedSeptember 21, 1886.

Application filed May 7, 1886. Serial No. 201,437. (No model.)

To all whom it may concern.-

Be it known that I, WILBUR F: HOWARD, of Glaremont, in the county ofSullivan and State of New Hampshire, have invented a new and usefulImprovement in Brushes, of which the following is a full, clear, andexact description.

My invention relates to an improved construction of brush, whereby asubstantial artiele'is producedin a simple and cheap way.

In the accompanying drawings, Figure 1 is a perspective view of a brushembodying my invention, part of the head-stock being broken away. Fig. 2is aplan of the under side of the I 5 brush 011 the line 3 3 Fig. 3;Fig.3, a crosssection through the head-stock on the line a: 00, Fig. 2;Fig. 4, an enlarged perspective view of the end fastening; Fig. 5, anenlarged crossseetion through the head stock on the line x w,

Fig. 2; and Fig. 6 is a view of a part of the core.

Similar letters of reference indicate corresponding parts.

In the drawings, A represents the handle 2 5 and B the head-stock of myimproved brush. Any suitable shape or outline may be given to theseparts, which may be made of one or more pieces. In the lower part of theheadstock one or more grooves, O, are cut of width and length adapted toreceivethe desired quantity'of bristles or other fiber or brushmaterial. The bristles D are out long enough to be introduced in thehead-stock doubled up, as shown, and to project therefrom to the desired5 length.

E is a grooved core, made of a strip of tin, sheet-iron, or othersuitable material, a little longer than the groove G in the head-stock,bent in U form. A portion of the back 01 40 core E, near each extremity,is cut away, so as to leave at each end of the strip two tongues,

a a, as shown in Fig. 6. The bristles D or other material are dividedinto bunches or parcels d, which are doubled over and arranged 4 5 alongthe back of the core E, being twisted at their centers at the same time.The first end bunches, e, are secured by the tongues'a a, which are bentback upon them in opposite directions, as shown clearly in Figs. 1 and2. When the entire length of the bar E has been filled up, the bunchesat that end are secured by the tongues a a. The filled core is then"forced into the groove 0, which is of size adapted to receive the coreE and bristles D, preferably with some degree of tightness. Pins,rivets, or screws 7) b b are passed from side to side laterally throughthe headstock B, core E, and bristles D, thus securingall the partsfirmly together. By this construction not only is the maximum ofsimplicity and strength attained, butthe necessity of piercing holes inthe top of thehead-stock is avoided. The twist given to the center ofeach bunch of bristles fastens them more securely in the head-stock. Thepins 1) b b passing through the bar E near 6 5 its ends andintermediately thereto impart great strength to the structure. Thebending back of the ends a a. a a of the core E, re-enforced by theinsertion into the groove 0, binds together the material and preventsthe end' fibers from coming out or working loose. The core E by itsconstruction presents a round-- ed smooth back or surface for thebristles to bear against, while it is far stiffer than a wire of equalthickness, and is better adapted to re- 7 5 ceive the fastening-pins b bI). This method of construction is applicable to brushes of any width orform. Any number of grooves of any shape may be made that the head stockwill accommodate. One set of tastening-pins will answer for any numberof grooves and rows of bristles. v 1

WVhat I claim as new, and desire to secure by Letters Patent, is

l. The brush composed of grooved head- 8 5 stock B, grooved core E,brush material D, and lateral pins 1) b in combination, substantially asshown and described.

2. The combination of core E, having oppositely-bent ends ad, withdoubled and twisted bunches of fiber d d, head-stock B, having grooveQand pins 1) b, passing laterally through all these parts, substantiallyas shown and described.

3. The U-shaped core E, with tongues 51 a 5 a a bent back as afastening-piece for bristles or other brush material, substantially asshown and described.
